​ ​ HUGO CHAVEZ Born into a working class family in Sabaneta, and after becoming dissatisfied with the Venezuelan political system which he viewed as corrupt and undemocratic, he founded the Revolutionary Bolivarian Movement in the early 1980s. Government of President Carlos Andrés Pérez ordered the violent repression of Chávez led anti government movements and eventually he was imprisoned in 1992. Getting out of prison after two years, he founded a social democratic political party, the Fifth Republic Movement, and was elected president of Venezuela in 1998. He subsequently introduced a new constitution which increased rights for marginalised groups and altered the structure of Venezuelan government. During his second presidential term, he introduced Communal Councils and worker-managed cooperatives, as well as a program of land reform, whilst also nationalising various key industries. He has supported Latin American and Caribbean cooperation and was instrumental in setting up the pan-regional Union of South American Nations, the Bolivarian Alliance for the Americas, the Bank of the South, and the regional television network TeleSur. NELSON MANDELA Mandela was an anti-apartheid activist, and the leader of Umkhonto we Sizwe, the armed wing of the African National Congress (ANC). In 1962 he was arrested and convicted of sabotage and other charges, and sentenced to life in prison. In prison, he and others performed hard labour in a lime quarry. Prison conditions were very basic. Prisoners were segregated by race, with black prisoners receiving the fewest rations. Political prisoners were kept separate from ordinary criminals and received fewer privileges. In February 1985 President P.W. Botha offered Mandela his freedom on condition that he 'unconditionally rejected violence as a political weapon'. Mandela refused the offer, releasing a statement via his daughter Zindzi saying "What freedom am I being offered while the organisation of the people remains banned? Only free men can negotiate. A prisoner cannot enter into contracts.'' On 2 February 1990, State President F. W. de Klerk reversed the ban on the ANC and other anti-apartheid organisations, and announced that Mandela would shortly be released from prison. Mandela was released from Victor Verster Prison in Paarl on 11 February 1990. On 27 April 1994 Mandela, as leader of the ANC, was inaugurated on 10 May 1994 as the country's first black President Source: Wikipedia.
